I dunno about the sales being useless. We got 2 LGW-MCO's in Oct return for ~820 quid total (ie £410/ticket) in the Jan sale, which I found a bargain, current prices same flights same days are in region of £6-700 each, and higher on other days. With gold giving free seat booking, lounge access, and even extra leg rooms seats, it's a relatively cheap 2nd holiday for us.
That said, my Gold will expire in Nov due to mostly the lack of the Mumbai route, which was 50% of my TP's on an average year. Of course that may change if work sends me on the possible 6-7 US trips over summer, but I somewhat doubt it! Mumbai is a route sadly I've ended up on BA for, as connecting via AMS to DL, although an option just doesn't jump out as convenient (and I won't fly JET for numerous reasonas). Connecting in India in Delhi, I may try if the costs are acceptable though.
